Question: If the picture in my instruction book shows a wire coil and my landing gear does not have a wire coil or vice versa... if the instruction book shows no wire coil and my landing gear has a wire coil... do I have the correct landing gear wire set for my model?

Answer: Most of the time yes. If the landing gear fits into the slots and accomodates the wheels and results in the correct ground height for your model you are going to be OK to use the landing gear provided with or without a coil in the gear.

Better Answer: The instruction books are laid up early in the production cycle of a model. At times we change the gear to add or remove a coil depending on what we learn from users. Ideally we would have it right from the get go but if we find that a landing gear is too "springy" in operational use, we take the coil out in the next run. Conversely if we find that the gear is too stiff in operational use, we add a coil in the next run. Either way, the main thing is that the gear fit correctly into the mounting slots and provide the correct ground height for your model when using the wheels provided.
